Safety during installation:
• During installation, ensure that the product’s components do not affect or limit vehicle functions. Avoid damaging these components!
• Only install undamaged parts in a vehicle!
• During installation, ensure that the product does not impair the field of vision and that it cannot
impact the driver’s or passenger’s head!
• A specialized technician should install the product. If you install the product yourself, wear
appropriate work clothing. Do not wear loose clothing, as it may get caught in moving parts.
Protect long hair with a hair net.
• When working on the on-board electronics, do not wear metallic or conductive jewelry such as
necklaces, bracelets, rings, etc.. If work on a running engine is required, exercise extreme
caution. Wear only appropriate work clothing as you are at risk of personal injury, resulting
from being crushed or burned.
• Before taking any action, disconnect the negative terminal on the battery, otherwise you risk a
short circuit. If the vehicle is supplied by auxiliary batteries, you must also disconnect the
negative terminals on these batteries! Short circuits can cause fires, battery explosions and
damages to other electronic systems. Please note that when you disconnect the battery, all
volatile electronic memories lose their input values and must be reprogrammed.
• If working on gasoline boat motors, let the motor compartment fan run before beginning work.
• Pay attention to how lines and cable harnesses are laid so that you do not drill or saw through
them!
• Do not choose to install the product in the mechanical and electrical airbag area!
• Do not drill holes or ports in load-bearing or stabilizing stays or tie bars!
• When working underneath the vehicle, secure it according to the specifications from the vehicle manufacturer.
• Note the necessary clearance behind the drill hole or port at the installation location. Required
mounting depth: 65 mm.
• Drill small ports; enlarge and complete them, if necessary using taper milling tools, saber saw,
keyhole saw or file. Debur edges. Follow the safety instructions of the tool manufacturer.
• Use only insulated tools, if work is necessary on live parts.
• Use only the multimeter or diode test lamps provided, to measure voltages and currents in the
vehicle/machine or ship. Use of conventional test lamps can cause damage to control units or
other electronic systems.
• The electrical indicator outputs and cables connected to them must be protected from direct
contact and damage. The cables in use must have sufficient insulation and electric strength
and the contact points must be safe from touch.
• Use appropriate measures to also protect the electrically conductive parts on the connected
consumer from direct contact. Laying metallic, uninsulated cables and contacts is prohibited.

Safety after installation:
•
•
•
•

Connect the ground cable tightly to the negative terminal of the battery.
Reenter/reprogram the volatile electronic memory values.
Check all functions.
Use only clean water to clean the components. Note the Ingress Protection (IP) ratings (IEC
60529).

Electrical connection:
• Note cable cross-sectional area!
• Reducing the cable cross-sectional area leads to higher current density, which can cause the
cable cross-sectional area in question to heat up!
• When installing electrical cable, use the provided cable ducts and harnesses, however, do not
run cables parallel to ignition cables or to cables that lead to large electricity consumers.
• Fasten cables with cable ties or adhesive tape. Do not run cables over moving parts. Do not
attach cables to the steering column!
• Ensure that cables are not subject to tensile, compressive or shearing forces.
• If cables are run through drill holes, protect them using rubber sleeves or the like.
• Use only one cable stripper to strip the cable. Adjust the stripper so that stranded wires are
not damaged or separated.
• Only use a soft soldering process or commercially available crimp connector to solder new
cable connections!
• Only make crimp connections with cable crimping pliers. Follow the safety instructions of the
tool manufacturer.
• Insulate exposed stranded wires to prevent short circuits.
• Caution: Risk of short circuit if junctions are faulty or cables are damaged.
• Short circuits in the vehicle network can cause fires, battery explosions and damages to other
electronic systems. Consequently, all power supply cable connections must be provided with
weldable connectors and be sufficiently insulated.
• Ensure ground connections are sound.
• Faulty connections can cause short circuits. Only connect cables according to the electrical
wiring diagram.
• If operating the instrument on power supply units, note that the power supply unit must be stabilized and it must comply with the following standard: DIN EN 61000, Parts 6-1 to 6-4.

If the instrument is mounted flush (i.e., from the
back so that the instrument glass and the panel
form one plane), the front ring must be removed.
Press the instrument glass with both thumbs,
while at the same time pressing the front ring forward from the instrument with both index fingers.
Note the use of a tool in the adjacent figure.

Place the flush mount seal A2C53215640
GB
on the instrument glass.
Put the instrument into the drill hole from the
back.
Adjust the instrument so that the gauge is level
and fasten it to the stud bolts on the rear side of
the panel, using the flush mount fixing bracket
A2C59510864.

Use the following connector to connect the
GB
instrument:
Connector set, 8-pin
- A2C59510850
The connector set is designed for a cable cross-section of 0.25 - 0.5 mm². For other cross-sections, please use contacts made by Tyco.
Single contacts:
Tyco No. 1355718-1 for 0.14 – 0.22 mm²
Tyco No. 963729-1 for 0.5 – 0.75 mm²
Strip:
Tyco No. 1355717-1 for 0.14 – 0.22 mm2
Tyco No. 963715-1 for 0.5 – 0.75 mm2
Create a crimp connection using the contacts and the
corresponding cables. Follow the instructions of the
hand pliers manufacturer.
Use the following for this:
Hand pliers Tyco No. 539635-1
And the tool Tyco No. 539682-2 for these hand pliers.
Pay special attention to whether the crimp barrel clutches all individual wires in the cable, otherwise you
risk a short circuit!

If you would like to omit the fastening nut, you
may use the part set A2C59510854 as an alternative. This is recommended if the installation location is subject to vibratory loads.
Screw the stud bolts into the provided drill holes
in the enclosure. Max. stud bolt torque is 1.5 Nm
